This site boasts over 650 petroglyphs covering a group of rockfaces within a small area. High concentrations of petroglyphs like this mark a place as hugely significant. The petroglyphs were created by ancestral Puebloan people living, farming, and hunting along the Puerco River between 650 and 2,000 years ago. Some of the ancient artists may have lived at Puerco Pueblo, located less than one mile north of this site.
